Title: Machining method for object by sandblast
Inventor: TANO TERUO
IPC: B24C3/22
Filed: 1985-08-06
Abstract: PURPOSE:To improve machining efficiency by making abrasives blown out of a jet nozzle to be carried on an air stream generated by the operation of a suction nozzle, thereby increasing the number of abrasives directly hitting the machined part and increasing the hitting speed. CONSTITUTION:By moving a slider, an object W is introduced into a machining chamber K and placed between a jet nozzle 3a and a suction nozzle 4b. Then a valve 19b is opened to draw air into a suction nozzle 4b and produce air stream around the object W. Under this condition, valves 17 and 18a are opened to make abrasives circulating through a bypass pipe 21 to be blown out of the jet nozzle 3a against the surface of the object W. Here, as the abrasives move, carried by the air stream generated around the object W, and the number of abrasives which directly hit the machined part of the object W including its edges, etc. is substantially increased, considerably improving the machining efficiency.

Abstract: PROBLEM TO BE SOLVED: To prevent a faulty image from being formed caused by a cleaning defect. SOLUTION: The back contrast of the paper non-passing area of a photorecept drum 1 is set to be larger than that of the paper passing area. In the paper non-passing area, the proper quantity of reversal toner is supplied to a nip between the drum 1 and a cleaning blade 51 from a developing sleeve 3a through the drum 1.
